Transgenerational experience can affect a range of natural enemies’ life-history traits and be involved in the control developmental plasticity. As major egg parasitoid spotted lanternfly, Lycorma delicatula (Hemiptera: Fulgoridae), wasp Anastatus orientalis (Hymenoptera: Eupelmidae) is effective at suppressing its host populations. The reproductive A. known to depend on photoperiod conditions,...
رودخانه یک پدیدۀ دینامیک است که مدام تغییر میکند. برآورد مقاومت ذرات رسوبی در مقابل فرسایش سبب شناسایی نقاط پایدار و ناپایدار در مناطق مختلف بستر رود خواهد شد. منطقۀ مطالعهشده رودخانۀ مسیلموچان در شهرستان آستانه است. این تحقیق با هدف بررسی آستانۀ حرکت فرسایش و رسوبگذاری ذرات و پایداری رسوبات در چهار مقطع از بستر این رودخانه بررسی شد. در ادامه، به منظور بررسی تنش برشی بحرانی و دبی واحد بحران...
Introduction. Over the past decades, laminated composites based on aluminum alloys have been increasingly used in aerospace and automotive industries. Laminated are usually produced by accumulative roll bonding, which results metallurgical bonding of initially prepared sheets. Hence, main task is to obtain a reliable bond between materials. However, at present, process joining similar or dissim...
The VPAC(2) receptor is a seven transmembrane spanning G protein-coupled receptor for two neuropeptides, vasoactive intestinal peptide (VIP) and pituitary adenylate cyclase-activating polypeptide (PACAP). It has a distinct tissue-specific, developmental and inducible expression that underlies an important neuroendocrine role. Here, we report the characterisation of the gene that encodes the mou...
Purpose of research is to develop and test a technique perform an experimental study the vibration strength D16 aluminum alloy joints welded applying resistance spot welding. Methods. Test coupons were made from 1 mm thick sheet blanks A feature proposed implementation symmetrical loading cycle. During tests, number cycles failure depending on range vibrations was recorded. Annealing thermomech...
BACKGROUND AND AIM: This study was carried out to compare three different ultrasonic cleaner devices in the cleaning process of endodontic instruments by scanning electron microscope (SEM). METHODS: In this study, 120 unused brand new hand and rotary instruments were examined after removing from the sealed package. The instruments were randomly divided into six groups of 20 rotary or hand files...
BACKGROUND Involvement of nitric oxide (NO) in the pathophysiology of human African trypanosomiasis (HAT) was analyzed in a HAT animal model (rat infected with Trypanosoma brucei brucei). With this model, it was previously reported that trypanosomes were capable of limiting trypanocidal properties carried by NO by decreasing its blood concentration. It was also observed that brain NO concentrat...
BACKGROUND Knee osteoarthritis (KOA) is the most prevalent form of knee joint disease and characterized by the progressive degeneration of articular cartilage. Although pathology of KOA remains unknown, genetic factors are considered to be the major cause. Asporin is a group of biologically active components of extracellular matrix (ECM) in articular cartilage, and asporin gene (ASPN) D-repeat ...
